"A Beautiful Mine"
After all these years, I finally realized that the theme music "A Beautiful Mine" by RJD2 seems to 'borrow' rather heavily from The Doors' "Riders on the Storm." No wonder that 'falling/cascading' section always seemed so familiar!
Much of David Carbonara's soundtrack for the show sounded very accurate to the era, but I always kind of wished they had also used music that sounded like something from 1961 for the main theme.
